Specification of Letters Patent.

Patented May 19, 1914i.

Application filed November 3, 1913. Serial No. 798,878.

To alleurom t may concern Be it known that I, DAVID C. BOYD, a citizen of the United States, residing at Galion, in the county of Crawford `and State of Ohio, have invented certain new and useful Improvements in Culver-ts, of which the following is a specification.

This invention relates generally to pipes and mains and more particularly to sheet metal culvert pipes for light culvert and drain use, the same being preferably corru- Oated. h The invention has for its primary object a simple strong, light, cheap, efficient, and all around serviceable corrugated culvert pipe which is formed out of semi-cylindrical sections of predetermined length, capable of being shipped in nesting relation with each other whereby freight charges are materially reduced, the parts being so constructed and arranged that they may be easily assembled at the point of installation so as to make a tight joint at the side seams to form a complete cylindrical pipe section and without the necessity of special tools or skilled labor.

l/Vith this and other objects in view, as will more fully appear as the description proceeds, the invention consists in certain constructions, arrangements, and combinations of the parts that I shall hereinafter fully describe and claim.

For a full understanding of the invention, reference is to be had to the following d escription and accompanying drawing, 1n whichd Y Figure l is a side elevation of a culvert pipe embodying the improvements of my invention; Fig. 2 is a fragmentary transverse sectional view thereof, and Fig. 3 is a detail perspective view of one of the brackets employed.

Corresponding and like parts are referred to in the following description and designated in all of the views of the accompanying drawing by like reference characters.

Referring to the drawing, the numeral 1 designates one of the semi-cylindrical corrugated pipe sections or parts preferably formed from a sterling galvanized metal sheet, each of said parts or sections being formed near both side edges and at predetermined points (longitudinally considered), with rivet holes to receive rivets 2 which pass therethrough and through corresponding openings formed in angular brackets 3 formed of cast metal.

In the manufacture of the semi-cylindrical sections or parts l, the brackets 3 are disposed transversely as shown and are formed with rounded base surfaces t which are designed to Iit snugly down in the hollow of one of the circumferential grooves or oorrugations where they are riveted in place. Preferably the opposite surfaces of the brackets are groovcd or recessed as indicated ill-1 l It is to be understood that in assembling two of the parts 0r sections l to form a complete cylindrical culvert pipe section, the side edges are overlapped to a predetermined extent, and for this purpose the brackets 3 are set back from the side edges a predetermined distance. They may both be set back the same distance or one slightly farther than the other, as desired. In order to provide for the overlap, one set of brackets on each semi-cylindrical section is formed on its base side and at the juncture of its two angularly disposed members with a recess G which is rounded as is the remaining portion of the base surface, these recesses receiving and accommodating the overlapping side edge of au adjoining semi cylindrical section, as clearly illustrated in the drawing. In order to secure the pairs of brackets together they are formed in their offset members with openings through which tie bolts 7 pass, being drawn up tight by nuts 8. While it is only necessary that one set of brackets for each semi-cylindrical section be formed with the overlap-receiving recess G, yet it is preferable in the manufacture of the parts to have both sets formed with such recesses, for then there will be no rights and lefts and the same castings may be used for both sides, interchangeably.

From the foregoing description in connection with the accompanying drawing, it will be understood that when these part-s leave the factory they will each comprise a semicylindrical corrugated sheet metal section to both side edges of which are riveted a predetermined number of brackets 3, whereby the parts may be nested in shipment and thereby reduce the freight charges and be easily and quickly connected together at the side seams by the tie bolts 7 to form at the point of installation, a complete cylindrical section with tight joints.

`What is claimed is l. A culvert pipe section adapted to mate.

with a corresponding section to form the pipe, the same being provided at its side edges and in set back relation thereto with angular brackets riveted thereto and provided With outstanding members formed With bolt receiving openings, said brackets being formed at the juncture of their angu-v lar members and on the base side thereof with `recesses adapted to receive the overlapping side edge of an adjoining section.

2. A culvert pipe made up cfa number of sections overlapping at their side edges, brackets riveted to said sections at the side edges thereof and set back from said side edges, said brackets being provided With outstanding members formed with bolt holes, and bolts extending through said holes yand tending to draw the brackets and sections together to form a tight side edge joint, one set of brackets being formed on their base sides and at the juncture of their angular members with recesses in which the overlapping side edge of the adjoining section lts, as and for the purpose set forth.

3. A sheet metal corrugated culvert pipe made up of a number of sections with longitudinal side seams, angular brackets riveted to the sections near the side edge thereof and set `back from said side edge, saidbrackets being formed with rounded base surfaces adapted to fit Within the hollow of the corrugations and with opposite grooved surfaces, the rivets setting down in said grooves and the oiiiset members of the Vbrackets being formed with bolt holes and the brackets being further formed on their base sides and at the juncture of their angularly disposed members with Y recesses adapted to receive snugly the overlapping side edge of an adjoining section, and tie bolts passing through the bolt holes of the brackets and ytending to draw the brackets and the sections together as and for the purpose set forth.

In testimony whereof I afliX my signature in presence of two Witnesses.

Y DAVID C. BOYD.
